====== 1.A.4.c iii - Agriculture/Forestry/Fishing: National Fishing ====== ===== Short description ===== In NFR sub-category //1.A.4.c iii// fuel consumption and emissions of Germany's maritime fishing fleet are reported. ^ Method ^ AD ^ EF ^ Key Category Analysis ^ | T1, T2 | NS, M | D, M, CS, T1, T2 | //no key category// | ===== Methodology ===== ====Activity Data ==== Primary fuel delivery data for national fishing is included in NEB lines 6 ('International Deep-Sea Bunkers') and 64 ('Coastal and Inland Navigation') for IMO-registered and unregistered ships respectively. The actual annual amounts used are therefore calculated within (Deichnik (2022)), where ship movement data (AIS signal) allows for a bottom-up approach providing the needed differentiation.[(DEICHNIK2022)] __Table 1: Annual fuel consumption, in terajoules__ | ^ 1990 ^ 1995 ^ 2000 ^ 2005 ^ 2010 ^ 2011 ^ 2012 ^ 2013 ^ 2014 ^ 2015 ^ 2016 ^ 2017 ^ 2018 ^ 2019 ^ 2020 ^ 2021 ^ ^ Diesel oil | 305 | 240 | 238 | 226 | 227 | 213 | 209 | 214 | 227 | 284 | 298 | 293 | 356 | 322 | 359 | 265 | ^ Heavy fuel oil | 33,3 | 26,0 | 26,0 | 24,4 | 24,5 | 23,0 | 22,6 | 16,8 | 13,8 | NO | NO | NO | NO | NO | NO | NO | | **Ʃ 1.A.4.c iii** ^ 338 ^ 266 ^ 264 ^ 250 ^ 251 ^ 236 ^ 232 ^ 231 ^ 241 ^ 284 ^ 298 ^ 293 ^ 356 ^ 322 ^ 359 ^ 265 ^ The strong increase after 2015 cannot be conclusively explained at the moment. However, even if the over-all fuel quantities delivered to the navigation sector would be somehow misallocated between the specific nautical acitivities, there would be no over- or under-estimation of over-all emissions. ==== Emission factors ==== The emission factors applied here, are derived from different sources and therefore are of very different quality. For the main pollutants, country-specific implied values are used, that are based on tier3 EF included in the BSH model [(DEICHNIK2020)] which mainly relate on values from the EMEP/EEA guidebook 2019 [(EMEPEEA2019)]. These modelled IEFs take into account the ship specific information derived from AIS data as well as the mix of fuel-qualities applied depending on the type of ship and the current state of activity. __Table 2: Annual country-specific emission factors, in kg/TJ__ | ^ 1990 ^ 1995 ^ 2000 ^ 2005 ^ 2010 ^ 2011 ^ 2012 ^ 2013 ^ 2014 ^ 2015 ^ 2016 ^ 2017 ^ 2018 ^ 2019 ^ 2020 ^ 2021 ^ | **DIESEL OIL** ||||||||||||||||| ^ NH3 | 0.32 | 0.32 | 0.32 | 0.32 | 0.32 | 0.32 | 0.32 | 0.32 | 0.32 | 0.32 | 0.32 | 0.32 | 0.32 | 0.32 | 0.32 | 0.32 | ^ NMVOC | 50.2 | 50.2 | 50.2 | 50.2 | 50.2 | 50.2 | 50.2 | 49.5 | 46.4 | 45.6 | 45.2 | 46.4 | 46.3 | 46.3 | 46.6 | 45.5 | ^ NOx | 1,139 | 1,139 | 1,139 | 1,139 | 1,139 | 1,139 | 1,139 | 1,139 | 1,172 | 1,172 | 1,174 | 1,164 | 1,172 | 1,170 | 1,171 | 1,181 | ^ SOx | 466 | 419 | 233 | 186 | 69.8 | 65.2 | 55.5 | 53.6 | 50.8 | 37.2 | 37.2 | 37.2 | 37.2 | 37.2 | 37.2 | 37.2 | ^ BC 2 | 83.7 | 75.3 | 41.8 | 33.5 | 12.5 | 11.7 | 11.7 | 12.3 | 12.3 | 12.5 | 12.7 | 12.4 | 12.2 | 12.0 | 11.6 | 11.5 | ^ PM 2.5 | 270 | 243 | 135 | 108 | 40.5 | 37.8 | 37.8 | 39.8 | 39.5 | 40.4 | 41.1 | 40.0 | 39.4 | 38.8 | 37.5 | 37.2 | ^ PM 10 | 289 | 260 | 144 | 115 | 43.3 | 40.4 | 40.4 | 42.6 | 42.3 | 43.2 | 43.9 | 42.8 | 42.1 | 41.5 | 40.1 | 39.8 | ^ TSP | 289 | 260 | 144 | 115 | 43.3 | 40.4 | 40.4 | 42.6 | 42.3 | 43.2 | 43.9 | 42.8 | 42.1 | 41.5 | 40.1 | 39.8 | ^ CO | 102 | 102 | 102 | 102 | 102 | 102 | 102 | 107 | 107 | 110 | 112 | 109 | 107 | 106 | 103 | 103 | | **HEAVY FUEL OIL** ||||||||||||||||| ^ NH3 | 0.33 | 0.33 | 0.33 | 0.33 | 0.33 | 0.33 | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | ^ NMVOC | 36.4 | 36.4 | 36.4 | 36.4 | 36.4 | 36.4 | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | ^ NOx | 1,258 | 1,258 | 1,258 | 1,258 | 1,258 | 1,258 | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | ^ SOx | 1,319 | 1,332 | 1,323 | 1,336 | 496 | 496 | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | ^ BC 2 | 64.9 | 65.5 | 65.1 | 65.7 | 24.4 | 24.4 | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | ^ PM 2.5 | 541 | 546 | 542 | 548 | 203 | 203 | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | ^ PM 10 | 595 | 601 | 597 | 602 | 224 | 224 | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | ^ TSP | 595 | 601 | 597 | 602 | 224 | 224 | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | ^ CO | 200 | 200 | 200 | 200 | 200 | 200 | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | 1 ratios PM2.5 : PM10 : TSP derived from the tier1 default EF as provided in [(EMEPEEA2019)] \\ 2 estimated from f-BCs as provided in [(EMEPEEA2019)]: f-BC (HFO) = 0.12, f-BC (MDO/MGO) = 0.31, chapter: 1.A.3.d.i, 1.A.3.d.ii, 1.A.4.c.iii \\ Navigation, Table 3-2 and Table A1 - BC fractions of PM emissions from relevant studies > **NOTE:** For the country-specific emission factors applied for particulate matter, no clear indication is available, whether or not condensables are included. > For information on the **emission factors for heavy-metal and POP exhaust emissions**, please refer to Appendix 2.3 - Heavy Metal (HM) exhaust emissions from mobile sources and Appendix 2.4 - Persistent Organic Pollutant (POP) exhaust emissions from mobile sources. ===== Trend discussion for Key Sources ===== > **NFR 1.A.4.c iii - National Fishing** is **no key source**. ===== Recalculations ===== With both **activity data and emission factors unaltered**, no recalculations occur against last year's submission. For **pollutant-specific information on recalculated emission estimates for Base Year and 2020**, please see the recalculation tables following [[general:recalculations:start|chapter 8.1 - Recalculations]]. ===== Uncertainties ===== Uncertainty estimates for **emission factors** were adopted from NFR 1.A.3.d i as a comparable emission source. =====Planned improvements ===== Besides a routine revision of the underlying BSH model, further focus will be put on the correct allocation of actvity data to the different navigation activities covered in different NFR sub-sectors. With respect to the strong increase in activity data from 2015 to 2016: This issue is under discussion with the BSH Hamburg as the agency in charge of the underlying model. However, these activity data are based on ship movement data showing a correspondingly increasing trend. Nonetheless, the model is under steady revision and erroneous calculations and results will be corrected whenever they are determined.
